1 tenth of 70kg is if you help thx
kkurt [141]

it would be 70/100 then it would go down to 7/10 so 1/10 of 70kg would be 7kg because you change 70 you make it a decimal witch is .70 or .7 now make that into a fraction and it would be 70/100 or 7/10 then you take your 7 because its 1/10 of 70. Or you could do it a whole lot easier way and just divide 70 by 10 and get 7. There you have it your answer is 7.

Solve: 4x + 6 = 8x - 18
sladkih [1.3K]

Answer:

x=-3

Step-by-step explanation:

4x+6=8x+18

We simplify the equation to the form, which is simple to understand  

4x+6=8x+18

We move all terms containing x to the left and all other terms to the right.  

+4x-8x=+18-6

We simplify left and right side of the equation.  

-4x=+12

We divide both sides of the equation by -4 to get x.  

x=-3
